Bund lining, bund repair & bund sealing upgrades with GRP fibreglass

Does your bund need lining?

Your bunds are exposed to tough conditions – but continued exposure to oils, chemicals and other liquids can make them crack, corrode, leak or become contaminated.

Bunds that aren't leak-free or safe can lead to expensive site damage, and if they breach Environment Agency pollution guidelines you could be fined tens of thousands of pounds.

Economical, durable fibreglass bund linings

Don't let this happen. Solve the problem for the long term and line your bunds with a fibreglass bund lining.

Fibreglass is long lasting and copes well with normal structural movement – and because it's impact resistant and easy to clean it'll remain maintenance free for many years to come.

Avoid expensive bund rebuilds

A fibreglass bund lining, also known as GRP lining, can mean the difference between a cost-effective bund repair and an expensive bund replacement.

We'll grit blast your bund and make any necessary repairs, upgrades or extensions. Next, we'll line your bund to create a long-lasting alternative to a complete bund rebuild.

Best of all, we'll normally have the job done within the week – so inconvenience is kept to a minimum.

Put these problems behind you with fibreglass bund lining...

Damaged Pipe LiningLeaking bund

If you see plants growing in the joins of a bund, it's not secure. When liquid fills the bund, it will leak out of the cracks the weeds have taken root in. A fibreglass bund lining will cover these weak points and make the bund safe once again.

Damaged Bund WallDamaged bund wall

Big cracks mean you've got serious safety issues on your hands. If a corrosive or toxic liquid filled this bund, it would gush out through the wall – fast. Repairs to the concrete combined with a GRP lining would soon put this bund back in action.

Contaminated Bund WallContaminated bund wall

When oils or acids drip or spill into a concrete bund, they penetrate any unprotected concrete and contaminate it. Fibreglass bund linings are durable, washable and provide better and longer-lasting protection than epoxy coatings.

Insecure BundUnsealed bund pipe

If you have an older bund with one or more pipes passing through the walls, the join can be a leak waiting to happen. You can solve the problem with a fibreglass reinforced lining, giving this particular weak point substantial protection.

Fibreglass Bund Lining Frequently Asked Questions

What is a Sui Generis Fibreglass Bund Lining System?

It literally involves building a new bund within the existing structure.

Following the required preparation to remove foreign matter, our four-coat lining system is hand applied to the existing structure. The finished lining has its own structural strength with a nominal thickness of 3mm.

Our Fibreglass Bund Linings are corrosion resistant, have excellent impact resistancy and are flexible enough to deal with structural movement.

My tank bund is leaking at the wall joints, how does a Fibreglass Lining
overcome this problem?

Our Fibreglass Lining has no joints or seams and therefore creates a complete seal making your bund impermeable to both water and the storage vessels contents.

But unlike other materials, there are no annual up-keep costs such as painting or treating. You're unlikely to have to worry about replacing it again.

Will the Fibreglass Lining need any maintenance?

No, just good housekeeping and the occasional clean to wash off dirt.

Do you use Sub-Contractors to carry out the installation?

Absolutely not, all the installation is carried out by our trained technicians.

How do you know that your Fibreglass Lining is suitable for my storage requirements?

Following the advice of our Chemist, the type of resins used for your fibreglass Lining is determined by the substance you are looking to contain and the operating environment of your bund.

Our linings can even be made suitable for some of the most aggressive chemicals and chemical mixes.

What kinds of liquids can a bund lining contain?

Our fibreglass bund linings contain most kinds of liquids, from toxic and corrosive solutions right through to aviation fuel or dairy products. These are just some of the bunds we can line for you:

  • Sodium Hypochlorite bund
  • Sodium Hydroxide bund
  • Urea bund
  • Sulphuric Acid bund
  • Transformer Oil bund
  • Gas Oil bund
  • Diesel Oil bund
  • Vegetable Oil bund
  • Acetic Acid bund
  • Sewerage bund
  • Chlorinated Water bund
  • Nitric Acid bund
  • Aluminium Sulphate bund
  • Hydrochloric Acid bund
  • Ethylene Glycol bund
  • Alcohols bund
  • Vinegar bund
  • Ethanol bund

What about the condition of the existing bund walls and floor?

Because it is reinforced and has its own structural integrity, of some substance, our Fibreglass Bund Lining is not wholly reliant on the existing substrate to remain sound.

If the substrate surface becomes flaky or crumbly any coating will lose its adhesion. With a Fibreglass Lining this is totally acceptable, even with massive de-lamination up to 80 or 90%.

Do you have to wait for ideal weather conditions before you can line my bund?

No, whilst most lining or coating systems demand all but perfect conditions and surfaces when being applied a Fibreglass lining system is very 'forgiving' and has a much wider tolerance to adverse conditions without its long-term value being undermined.

Consequently, a Fibreglass Lining system can usually be installed all year round to meet your requirements and not that of the weather.

How long does the Lining take to cure?

Our Linings will be cured within the hour.

Will you keep my site tidy?

It will be necessary to have materials on site but our operatives are fully aware of the importance of good housekeeping and all materials will be safely stored.

Our work areas will be left clean and tidy when we depart from site and the only evidence of our visit will be our Fibreglass Lining.

Will I be able to find a cheaper bund lining quote?

Possibly, we do acknowledge that our price may not always be the most economical, but we are confident that our commitment and proven track record for offering excellent customer service and quality of product whilst also conforming to the highest Health and Safety standards more than compensates for this and offers it own unique value.

However, if you do receive a more competitive quote please provide us with the details and we will see if we can help.

Do your bund linings and repairs conform to regulations?

Yes. Bunds and bund repairs have to conform to stringent pollution control regulations, which are there to ensure secondary containment is of sufficient size, oil-tight, contains no direct outlet and has no pipework passing through it if avoidable.

Our bund repairs and upgrades all comply with current Pollution Prevention Guidelines (PPG2) and SEPA (Scottish Environment Protection Agency) regulations.

What quality accreditations do you have?

ISO 9001: 2008, having first achieved ISO 9001 accreditation in 2002 our Quality Management System and associated procedures are now firmly ingrained into our everyday practices, this combined with the fact that many of our site operatives have been with us for over a decade means that stringent quality control has become second nature to us ensuring that you will be left with a product of the highest quality.
